"Loud speaker" for ORATOR should be "Stentor." Orators are not "loud" by definition."One sitting in your lap, perhaps" for TOYDOG is weak because we don't use the term "toy dog"; we say "toys." (It's possible, I guess, to say toy dog to differentiate it from a toy bitch.) A better clue would be "Found on a kid's bed, perhaps."

I think "Training site?: Abbr." for STN refers to stations or areas in gymnasia.
